    Is a warmer Arctic a canary of global warming? Since the 1970s the northern polar region has warmed faster than global averages by a factor or two or more, in a process of 'Arctic amplification' which is linked to a drastic reduction in sea ice.

    But then how to...]]> Tue, 30 May 2017 19:02:33 -0400 Thawing permafrost will release powerful greenhouse gas nitrous oxide http://arctichub.net/blog/2017/05/thawing-permafrost-will-release-powerful-greenhouse-gas-nitrous-oxide http://arctichub.net/blog/2017/05/thawing-permafrost-will-release-powerful-greenhouse-gas-nitrous-oxide
